Abstract
A method for determining a cell voltage of a battery cell of a traction battery of a vehicle includes filtering the cell voltage of the battery cell by a filtering device, sampling the filtered cell voltage by an analogue to digital converter, transferring the filtered and sampled cell voltage as a cell voltage signal to a computing device, evaluating the cell voltage signal by the computing device, determining a ripple value which describes a ripple of the cell voltage, and evaluating the cell voltage signal depending on the ripple value.
